No birthday would be complete without a throwback photo—something January Jones clearly agrees with. In honor of her 38th year, she took to Instagram to share an adorable picture of herself as a toddler, and it's pretty priceless.

In the throwback, the Mad Men star poses for the camera wearing an "I am a Sesame Street Kid" sweater. Her getup is pretty cute on its own, but it's her bowl cut and bangs that really seal the deal (below). To accompany the double-tap-worthy shot, Jones makes a very solid birthday announcement.

"On this day of my birth I would like to declare that I refuse to grow up, and that I'd like life to stop making me try," she wrote. "Instead I'm going to feel emotions deeply, have tantrums when I feel life unfair, not always do things in moderation, and make a big mess sometimes.. I want to run with abandon and laugh until I breathe in gasps, I will love unconditionally and sometimes be afraid of the dark. I was once told that you are as old as you feel, so if that's true, Mom & Dad I'm gonna need this sweater back." Well said, January.
